ABSTRACT:
The present invention relates to an apparatus for treating and regenerating a spent caustic solution at ambient temperatures which includes means for oxidizing the spent caustic stream with an air/ozone gas mixture, followed by irradiating the oxidized spent caustic stream with a broad range of ultraviolet radiation and finally filtering the spent caustic solution.
